Item description:

Go forward and pick up the treasure
(Watch out for the crusher coming down)

Once done, go over to the opposite side
(you'll know by the mummies that show up when you get there)

Kill them, and proceed by turning left and go up the stairs/steps

When you turn a sharp right, a gold plate will show for you to shoot

Stand on the platform first and shoot the gold plate

Once it turns, just follow your way through,
the gold treasure will be sitting on a table
